It didn't take long for Woods's story to go viral. Hundreds showed up on the beach and Woods told Pirate FM that he received supporting messages from people all over the world—people who couldn't be there with Walnut even told him they'd be walking their own dogs at the same time in his honor.

Walnut's story traveled through social media with the hashtags #WalkWithWalnut and #WalnutsLastWalk.

After the final walk, Woods posted on Facebook that Walnut had been put to sleep just hours later. Walnut died surrounded by his family in Woods's arms.

Though Walnut is no longer with Woods, his legacy lives on. Ethical Record Label released the charity single "Walk With Walnut" by Gee Kenny, with 100 percent of the proceeds going to the Battersea Dogs and Cats home.

"Thank you to the hundreds of people that attended the walk this morning and to all those that had their own walks with their beloved pets..." Woods wrote on Facebook. "I also want to thank the wonderful people of Newquay for their support which I will never forget as long as I live."

One of the best traditions in the NHL is when a special guest gets to drop the puck in the ceremonial faceoff just before the game. It’s even better when a dog—nay, a hero dog—participates and then gets to bask in the applause afterward.
